EMBROIDERING FRAME AND STAND.

SPECIFICATION forming part of Letters Patent No. 383,533, dated httay 29, 1888.

Application filed March 3, 1887.

To aZZ whom it may concern.-

Be it known that I, HERMANN O. LUDWIG,

of the city, county, and State of New York,

have invented certain new and useful Improvements in Embroidering Frames and Stands, of which the following is a specification.

This invention relates to an embroideryframe which may be used on an adjustable stand, or separately therefrom, according to the size and nature of the work.

In the accompanying drawings, Figure 1 represents a perspective view of my improved embroidcringframe. Figs. 2, 3, and 4 are details of one of the stretching-clamps for later ally stretching the fabric on the frame. Figs. 5 and 6 are details, drawn on a larger scale, showing the connection of one of the stretching-rollers with the extension-braces and supportingstand. Fig. 7 is a vertical transverse section of one of the stretching-rollers, and Fig. Sis a plan of my improved embroidering-frame.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the supporting-stand ofmy improved embroidering-frame, which stand is composed of two pairs of intercrossing legs, a a, which are provided with a number of holes, through which the pivot ends of a transverse connecting-rod, a, are passed, each pair of legs being clamped thereto by washers and thumbnuts, so as to be firmly held in position. By the holes arranged in the legs the supporting-frame may be set in different positions, as required by the size and inclination of the cmbroideringframe supported by the same. At the upper ends of the legs a a are bearings for the end pivots of the stretching-rollers B B, each of which is com posed of two parts, the lower half being provided with projecting pins 1), that are secured to alongitudinal strip, 1), glued into a groove, V, of the lower half, while the upper half of each roller is provided with socket-holes b for said pins, as shown in Fig. 7.

The fabric to be stretched on the frame is placed on the pins of the lower half of the rollers,and the upper half of the rollers placed over the fabric and secured to the lower half by strong rubber rings at, that are seated in annular-grooves d of said sections, as shown Serial No. 229,532. (No model.)

in Fig. 6. When it is desired to take the roller sections apart, so as to detach the fabric or apply a new one, the rubber rings are rcmoved from the roller-sections and placed into annular grooves (2 which grooves are formed in the solid end portions of the lower half of the rollers, as shown in Fig. 6.-

The end pivots, c, of each stretching-roller B are provided with two sets of radial holes or perforations, e e", the outer set, 0, being engaged by a pivoted hook, e, or other suitablelockin g device of extensioubraces 0, when the stretching-rollers are adjusted on the sup porting-stand'A. The ends of the extension braces O are applied to the end pivots, e, of the rollers B, and made of two perforated pieces which are guided alongside of each other by metallic keepersf and pinsf at the end of the pieces, as shown in Figs. 1 and 8. The second inner set of holes, 0', serves to lock the extension-braces G to the rollers B B when the latter are detached from the supporting stand A, when it is preferred to use the frame without the stand-as, for instance, when the fabric to be embroidered is larger than the stand, or when it is not convenient to carry the frame.

The fabric to be embroidered is stretched on the rollers E13 by means of thelocking devices described, the embroidered portion of the fabric being gradually wound upon one roller while the unembroidered fabric is unwound from the other roller, as customary in embroidering-framcs of this class. To impart, also, a stretching action on the fabric in a lateral direction, so as to remove the puckerings imparted to the fabric by the longitudinal strain on the same, two stretching-clamps, D D, are employed, which are shown in detail in Figs. 2, 3, and 4, and which consist of two jaws, g g, of which one is provided with fixed pins, the other with holes for said pins, said jaws being connected by a lever-hinge, g, the outer ends of which are slotted and applied to a leather strap, g that is passed around the extension side braces, O G, as shown in Figs. 1' and 8. For tightening the fabric theleather straps are adjusted and the jaws of the stretching-clamps tightly applied to the fabric,whereby the same is reliably stretched in lateral direction.

The peculiar construction of thelever-hinge strip inserted in said groove, said striphaving employed is clearly shown in Figs. 2, 3, and fixed pins, and the other semi-cyllndrrcal sec- 4, though I do not confine myself to this contion being provided wlth sockets for sa1d p1ns, 15 struction, as any other equivalent hinge consubstantially as described. I

5 struction of the jaws may be employed. In testimony thatI claim the foregoing as my Having thus described myinvention, Iclaim 1 invention I have signed my name in presence as new and desire to secure by Letters Patentof two subscribing witnesses.
